网络检测工具smokeping安装配置

smokeping是MRTG和RRDtool作者Tobi Oetiker的作品，主要用于对IDC网络质量，稳定性等做检测，主要功能包括常规的ping，dig，echoping，curl等，依赖rrdtool来画图。选择smokeping我觉得有以下原因：

1，最佳的画图功能，延迟和丢包用颜色和阴影表示很直观。

2，免费和开源。

3，支持主从的分布式模式。

4，可以自定义报警功能。

smokeping官方网站：http://oss.oetiker.ch/smokeping/

如下安装配置的系统为:redhat 5.8 + Perl 5.8.8

smokeping官方对perl版本要求：Perl 5.8.8 or later

一，安装

官方下载地址：http://oss.oetiker.ch/smokeping/pub/

1，安装yum源，这个rpmforge源中有smokeping所需的依赖包：

# rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

安装成功之后会在yum仓库配置中多一个repo文件：

[root@yd_82_215 soft]# ls /etc/yum.repos.d/
5AS.repo  5ASU5.repo  mirrors-rpmforge  redhat.repo  rhel-debuginfo.repo  rpmforge.repo

2，安装依赖包：

# yum install httpd

# yum install rrdtool

# yum install fping

# yum install echoping

# yum install curl

# yum install perl perl-Net-Telnet perl-Net-DNS perl-LDAP perl-libwww-perl perl-RadiusPerl perl-IO-Socket-SSL perl-Socket6 perl-CGI-SpeedyCGI

3，安装最新版smokeping：

# wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.6.9.tar.gz

# tar xf smokeping-2.6.9.tar.gz 

# cd smokeping-2.6.9/

# ./configure --prefix=/opt/smokeping

注意：

1，configure之后，如果依赖的perl module没有安装好，会提示用脚本进行安装。根据提示，直接运行脚本即可。如果脚本运行之后，仍然有问题，参考第2条

2，如果configure时候，出现如下报错，则是FCGI模块没有安装：

checking checking for perl module 'FCGI'... Failed
checking checking for perl module 'CGI'... Ok
checking checking for perl module 'CGI::Fast'... Failed

安装FCGI模块：

# perl -MCPAN -e 'install FCGI'

如果提示未安装cpan，则用yum进行安装

# yum install cpan

然后在安装：

# ./configure --prefix=/opt/smokeping

# make install

查看安装目录：

[root@yd_82_215 smokeping]# ls
bin  etc  htdocs  lib  share  thirdparty

4，在smokeping目录中有很多以dist结尾的配置文件，需要把dist结尾的文件重命名，配置才能生效：

# cd htdocs

# cp smokeping.fcgi.dist smokeping.fcgi

# cp tr.cgi.dist tr.cgi

# cd ../etc/

# cp config.dist config

# cp basepage.html.dist basepage.html

# cp smokemail.dist smokemail

# cp tmail.dist tmail

# cp smokeping_secrets.dist smokeping_secrets

# chmod 600 /opt/smokeping/etc/smokeping_secrets

二，修改smokeping和apache配置文件

1，修改二进制命令权限：

# chmod 4775 /bin/traceroute

2，建立下面三个目录用于保存smokeping的数据等

# mkdir /opt/smokeping/data

# mkdir /opt/smokeping/var

# mkdir /opt/smokeping/htdocs/cache

# mkdir -p /opt/smokeping/htdocs/img

# chown -R apache:apache /opt/smokeping

3，指定rrdtool的perl模块库文件路径

先找到系统上库文件位置：（不同系统或者不同的perl-rrdtool的安装方法，位置会不同）

[root@yd_82_215 ~]# rpm -qa|grep rrdtool
perl-rrdtool-1.4.7-1.el5.rf
rrdtool-1.2.27-4.el5
rrdtool-1.4.7-1.el5.rf

[root@yd_82_215 ~]# rpm -ql perl-rrdtool-1.4.7-1.el5.rf
/usr/lib/perl5/vendor_perl/5.8.8/RRDp.pm
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/RRDs.pm
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/RRDs/RRDs.bs
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/RRDs/RRDs.so
/usr/share/doc/perl-rrdtool-1.4.7
/usr/share/doc/perl-rrdtool-1.4.7/MANIFEST
/usr/share/doc/perl-rrdtool-1.4.7/README
/usr/share/man/man3/RRDp.3pm.gz
/usr/share/man/man3/RRDs.3pm.gz

# vim /opt/smokeping/bin/smokeping_cgi

把如下行：

#use lib qw(); # PERL5LIB

修改为：
use lib qw(/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/RRDs); # PERL5LIB

4，修改apache配置文件

# vim /etc/httpd/conf/httpd.conf 

添加下面虚拟主机： 

<VirtualHost *:80>
    ServerAdmin root@localhost
    ServerName 10.13.82.215
    DocumentRoot /opt/smokeping/htdocs
    ErrorLog logs/174-error_log
    CustomLog logs/174-access_log common
    <Directory "/opt/smokeping/htdocs">
      Options FollowSymLinks ExecCGI
      AllowOverride None
      DirectoryIndex index.html smokeping.fcgi
      AddHandler cgi-script fcgi .cgi
      Order allow,deny
      Allow from all
      </Directory>
</VirtualHost>

重启apache：

# /etc/init.d/httpd restart

5，修改smokeping配置文件

# vim config

mailhost = mail.com

#如下所示，定义多个FPing，然后在最下面node定义的时候（如下配置中的红色字体），使用不同的probe，就实现了探测的多进程，多与机器多的检测，提升了效率。

++ zong_yd_eth1
menu = 移动机房外网_汇总 
title = yd--->移动机房外网_汇总
host = /net_yd_eth1/baidu_node /net_yd_eth1/sohu_node

注意：

1）,配置文件如果有中文的话，不仅如上配置文件中要设置charset=UTF-8，系统也要设置中文字符集在/etc/profile中加入export LANG=zh_CN.UTF-8，并且所有的xshell或者crt中断也要设置成utf-8格式，这样就不会影响中文在配置文件中的编辑和中文在访问页面的展示。

2）,配置的详细信息可以参考官方网站：http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html

6，重启脚本定制

# vim /etc/init.d/smokeping

添加如下内容：

#!/bin/bash
#
# chkconfig: 2345 80 05
# Description: Smokeping init.d script
# Hacked by : How2CentOS - http://www.how2centos.com
# Get function from functions library
. /etc/init.d/functions
# Start the service Smokeping
start() {
        echo -n "Starting Smokeping: "
        /opt/smokeping/bin/smokeping >/dev/null 2>&1
        ### Create the lock file ###
        touch /var/lock/subsys/smokeping
        success $"Smokeping startup"
        echo
}
# Restart the service Smokeping
stop() {
        echo -n "Stopping Smokeping: "
        kill -9 `ps ax | grep "/opt/smokeping/bin/smokeping" | grep -v grep | awk '{ print $1 }'` >/dev/null 2>&1
        ### Now, delete the lock file ###
        rm -f /var/lock/subsys/smokeping
        success $"Smokeping shutdown"
        echo
}
### main logic ###
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  status)
        status smokeping
        ;;
  restart|reload|condrestart)
        stop
        start
        ;;
  *)
        echo $"Usage: $0 {start|stop|restart|reload|status}"
        exit 1
esac
exit 0

增加执行权限

# chmod +x /etc/init.d/smokeping

7，smokeping服务启动

正常启动：

# /etc/init.d/smokeping start

或

# /opt/smokeping/bin/smokeping

调试故障时，使用debug模式启动：

/opt/smokeping/bin/smokeping --config=/opt/smokeping/etc/config --debug

三，访问页面

http://10.13.82.215/

页面效果如下：
